# SYNOPSIS

#include <security/pam_appl.h>

int
pam_get_item(const pam_handle_t *pamh, int item_type, const void **item);

# DESCRIPTION

The pam_get_item() function stores a pointer to the item specified by the item_type argument in the location pointed to by the item argument. The item is retrieved from the PAM context specified by the pamh argument. If pam_get_item() fails, the item argument is untouched.

The following item types are recognized:

PAM_SERVICE
  The name of the requesting service.
PAM_USER
  The name of the user the application is trying to authenticate.
PAM_TTY
  The name of the current terminal.
PAM_RHOST
  The name of the applicant's host.
PAM_CONV
  A struct pam_conv describing the current conversation function.
PAM_AUTHTOK
  The current authentication token.
PAM_OLDAUTHTOK
  The expired authentication token.
PAM_RUSER
  The name of the applicant.
PAM_USER_PROMPT
  The prompt to use when asking the applicant for a user name to authenticate as.
PAM_AUTHTOK_PROMPT
  The prompt to use when asking the applicant for an authentication token.
PAM_OLDAUTHTOK_PROMPT
  The prompt to use when asking the applicant for an expired authentication token prior to changing it.
PAM_HOST
  The name of the host the application runs on.
PAM_SOCKADDR
  The sockaddr_storage of the applicants's host.
PAM_NUSER
  The “nested” user if this is a login on top of a previous one.

See pam_start(3) for a description of struct pam_conv.
